3-Oxo-rhazinilam:  A New Indole Alkaloid from <i>Rauvolfia serpentina</i> × <i>Rhazya stricta </i>Hybrid Plant Cell Cultures

Abstract

A new monoterpenoid indole alkaloid, 3-oxo-rhazinilam (1), was isolated from intergeneric somatic hybrid cell cultures of Rauvolfia serpentina and Rhazya stricta, and the structure was determined by detailed 1D and 2D NMR analysis. It was also proved that 3-oxo-rhazinilam (1) is a natural constituent of the hybrid cells.
